  摘要：

  A bicyclic scaffold derived from the natural monosaccharide D-glucose, and possessing several diversity sites, was linked to various resins through the primary (C-6) hydroxyl and decorated on the solid phase: the hydroxyl group at C-4 was functionalized as ester, ether, and carbamate, the amino group ill the second cycle (C-3' position) was functionalized as amide, sulfonamide, and ureido- and thioureido-derivatives. The compounds synthesized oil the solid phase were tested for their antiproliferative activity oil tumor cell lines. (c) 2006 Elsevier Ltd. All rights reserved.

  α-stereoselective synthesis of deoxyglycosides using cooperative Brønsted acid-type organocatalysis has been developed. The method is tolerant of a wide range of glycoside donors and acceptors, and its versatility is exemplified in the one-pot synthesis of a trisaccharide. Mechanistic studies suggest that thiourea-induced acid amplification of the chiral acid via H-bonding is key for the enhancement

  2‐Deoxy sugars and their derivatives occur abundantly in many pharmaceutically important natural products. However, the construction of specific 2‐deoxy‐glycosidic bonds remains as a challenge. Herein, we report an efficient way to prepare 2‐deoxy‐α‐glycosides by glycosylation of 2‐iodo‐glycosyl acetate and subsequent visible‐light‐mediated tin‐free reductive deiodination. We have successfully applied

  Protecting groups play multiple and vital roles during the synthesis of carbohydrates and other natural products. We herein report the installation and orthogonal cleavage, under mild conditions, of a 4-(tert-butyldiphenylsilyloxy)-2,2-dimethylbutanoyl (BDMB) group as a sterically hindered pivaloyl-type hydroxy protecting group. The compatibility of this substituent with the removal of other protecting

  that applies unique features of highly electrophilic boron catalysts, such as tris(pentafluorophenyl)borane, in addressing a number of the current limitations of methods in glycoside synthesis. This approach utilizes glycosyl fluoride donors and silyl ether acceptors while tolerating the Lewis basic environment found in carbohydrates. The method can be carried out at room temperature using air- and moisture

  寡糖和糖缀合物中糖苷键组装方面的挑战是实现糖科学进步的显着前景的瓶颈。在这里，我们报告了一种策略，该策略应用了高亲电性硼催化剂（如三（五氟苯基）硼烷）的独特特性，以解决目前糖苷合成方法的一些局限性。这种方法利用糖基氟供体和甲硅烷基醚受体，同时耐受碳水化合物中发现的路易斯碱性环境。该方法可以在室温下使用空气和水分稳定形式的催化剂进行，负载量低至 0.5 mol%。这些特征使得可以访问广泛的糖基化模式，包括葡萄糖、甘露糖和鼠李糖系列中的所有 C1-C2 立体化学关系。这种方法允许一锅、迭代糖基化直接从单糖构建块生成寡糖。这些进步使得能够从简单的构建单元中快速且通过实验直接制备复杂的寡糖单元。
